Understand where facility water goes — and what it costs.
Browser-based calculators and practical guides for benchmarking, budgeting, leak-loss scenarios, fixture planning, submeter reconciliation and water-efficiency projects.
Useful numbers, visible assumptions
These tools are built for early-stage planning and operational review. You supply the rates, quantities, periods and performance assumptions that belong to your situation; the site shows the arithmetic and explains what can change the result.

Open →Built for international use
Most tools avoid hard-coding currency, utility rates, labour rates, legal thresholds or regional benchmarks. Use consistent units and the rates that apply where you operate.
Editorial approach
We favour primary government, standards and technical sources for definitions and safety boundaries.
